CLN1 disease is a rare genetic condition that affects the nervous system. Also known as infantile neuronal ceroid lipofuscinosis, this disease is typically characterized by the onset of symptoms in infancy. It is caused by mutations in the CLN1 gene, which impairs the function of certain enzymes involved in the breakdown of long-chain fatty acids. As a result, a build-up of lipopigment materials occurs in the cells, leading to the degeneration of neurons and the progressive loss of neurological function.

Patients with CLN1 disease experience a variety of symptoms, including myoclonus (muscle jerks), seizures, and progressive loss of motor and cognitive skills. The disease follows a rapid and devastating course, usually leading to death in early childhood or adolescence. The frequency and severity of symptoms can vary between patients, with some individuals experiencing a slower disease progression.

Research on CLN1 disease is ongoing, and scientific studies are aimed at understanding the underlying mechanisms of the disease and developing potential therapies. Clinical trials are being conducted to test various treatment approaches, including gene therapy and enzyme replacement therapy. Additional information about ongoing research and clinical trials can be found on websites such as ClinicalTrials.gov and OMIM.

Support and advocacy organizations play a crucial role in providing resources and support for patients and families affected by CLN1 disease. These organizations work to raise awareness about the disease, provide information and resources, and support research efforts. Patients and families can also find additional information about CLN1 disease in scientific articles and references available on PubMed and other online catalogs and databases.

Frequency

CLN1 disease, also known as Infantile Neuronal Ceroid Lipofuscinosis (INCL), is a rare genetic disorder that affects the nervous system. It is one of a group of diseases collectively known as Batten disease. CLN1 disease is caused by mutations in the gene named CLN1, which impairs the function of certain enzymes in cells that help break down waste materials. As a result, lipofuscin, a waste material, accumulates in cells, leading to the death of nerve cells.

The frequency of CLN1 disease is very low, with only a few hundred cases reported worldwide. This makes it a rare disease. CLN1 disease is typically diagnosed in infants, as symptoms such as infantile myoclonus (muscle jerks) and developmental regression usually appear between 6 months and 2 years of age.

Americans see their primary care doctors less often than they did a decade ago. Adults under 65 made nearly 25% fewer visits to primary care providers in 2016 than they did in 2018, according to National Public Radio. In the same time period, the number of adults who went at least a year without visiting a primary care provider increased from 38% to 46%.

Research and scientific studies on CLN1 disease are ongoing to learn more about its causes, inheritance pattern, and function of the CLN1 gene. Resources such as the CLN1 Disease Center provide information and support for patients and their families. Additional information can be found on websites such as PubMed, OMIM, and clinicaltrials.gov, which catalog scientific articles, genes associated with CLN1 disease, and ongoing clinical trials.

Support and advocacy groups for CLN1 disease, such as the Batten Disease Support and Research Association, also provide resources and information for patients and their families. Genetic testing is available to confirm a diagnosis of CLN1 disease and distinguish it from other similar diseases.

Further research is needed to understand the frequency of CLN1 disease in different populations and to develop effective treatments. Clinical trials and studies continue to explore potential therapies and interventions for this rare and devastating condition.

Causes

The CLN1 disease, also known as infantile neuronal ceroid lipofuscinosis (INCL), is caused by mutations in the CLN1 gene. This gene is responsible for producing the enzyme palmitoyl-protein thioesterase 1 (PPT1), which is crucial for breaking down certain fats in the body.

When the CLN1 gene is mutated, it impairs the function of PPT1, leading to the accumulation of lipofuscin, a fatty substance, in the cells of the nervous system. This buildup of lipofuscin ultimately results in the progressive deterioration of brain cells and the characteristic symptoms of CLN1 disease.

CLN1 disease follows an autosomal recessive inheritance pattern, meaning that individuals must inherit two copies of the mutated CLN1 gene, one from each parent, to develop the condition. Carriers, who have only one copy of the mutated gene, typically do not show any symptoms of the disease.

The CLN1 gene is one of several genes associated with a group of rare genetic disorders collectively known as neuronal ceroid lipofuscinoses (NCLs). Each NCL subtype is caused by mutations in a different gene, resulting in distinct clinical features and disease progression patterns. CLN1 disease, specifically, is characterized by the onset of symptoms in infancy, including seizures, myoclonus (muscle spasms), reduced muscle tone, and cognitive and motor decline.

More information on the genetics of CLN1 disease, as well as other NCL subtypes, can be found in scientific articles available on PubMed and resources such as OMIM (Online Mendelian Inheritance in Man) and clinicaltrialsgov. These resources also provide support for genetic testing, clinical trials, and advocacy for patients and their families.

Learn more about the gene associated with CLN1 disease

The CLN1 disease, also known as infantile neuronal ceroid lipofuscinosis (INCL), is a rare genetic condition that primarily affects the nervous system. This condition is caused by mutations in the CLN1 gene, which impairs the normal function of certain cells in the body.

The CLN1 gene, also referred to as the ceroid-lipofuscinosis, neuronal 1 gene, is located on chromosome 1p32. Mutations in this gene lead to the accumulation of lipofuscin, a fatty substance, in the cells of the brain and other tissues.

Individuals with CLN1 disease typically have an onset of symptoms in the first year of life. These symptoms include developmental regression, myoclonus (rapid, involuntary muscle jerks), and seizures. The disease progressively worsens, leading to severe intellectual and motor disability, and ultimately premature death.

The CLN1 gene is one of several genes associated with a group of rare inherited disorders collectively known as neuronal ceroid lipofuscinoses (NCLs). There are different forms of NCLs, each caused by mutations in a different gene. Mutations in the CLN1 gene are responsible for the infantile form of the disease, while mutations in other genes cause different forms of NCLs.

To learn more about the CLN1 gene and the condition it causes, there are several scientific resources available. The Online Mendelian Inheritance in Man (OMIM) database provides comprehensive information about the CLN1 gene and associated diseases. PubMed, a database of scientific articles, also contains numerous references to studies and research on CLN1 disease.

This rare genetic condition primarily affects the nervous system and leads to severe neurological impairment and early death. Understanding the function of the CLN1 gene and its associated disease can lead to improved diagnosis, testing, and treatment options for individuals affected by CLN1 disease.

Inheritance

The CLN1 disease, also known as infantile neuronal ceroid lipofuscinosis (INCL), follows an autosomal recessive inheritance pattern. This means that both copies of the gene associated with the disease must be mutated in order for an individual to develop the condition.

INCL is caused by mutations in the PPT1 gene, which provides instructions for producing an enzyme called palmitoyl-protein thioesterase 1. This enzyme is responsible for breaking down a fatty substance called lipofuscin, which accumulates in cells of the nervous system.

When both copies of the PPT1 gene are mutated, the enzyme is unable to function properly. This impairs the breakdown of lipofuscin, leading to its accumulation in cells throughout the body.

Patients with INCL typically have a very short life expectancy and usually die in early childhood. The disease is characterized by severe neurological symptoms, including rapid loss of cognitive and motor function, myoclonus (involuntary muscle jerks), and seizures.

INCL is one of several rare diseases collectively known as the neuronal ceroid lipofuscinoses (NCLs). Each NCL has a different genetic cause and presents with unique symptoms, but all share a similar pattern of neurodegeneration.
